Drought Resistant Plant Festival Water Wise - Money Wise Sponsored by the Los Angeles Cactus and Succulent Society DATES PLACE Saturday, March 27-9:00 A.M. to 5:00 P.M. Sunday, March 28-9:00 A.M. to 4:00 P.M. Sepulveda Garden Center, 16633 Magnolia Boulevard, Encino THEME Landscaping with cacti and succulents - To improve ways to fulfill the Club's mission statement of "education, conservation and the study of cacti and succulents". In the past our show and sale has concentrated on the educational aspect with our extremely successful informational exhibits. The current approach will be to educate and demonstrate how cacti and succulents have had all of these qualities long before it was necessary and how these plants fit into landscape design with other plants. SHOW AND SALE FORMAT The show will consist of landscaping exhibits constructed by the club and vendors. The exhibit themes are Cacti & Succulents, Succulents and Native Plants, Pet & Child Friendly Plants and Color Coordinated. The festival committee is asking members to loan plants to populate the Club exhibits. We need 6" to 5 gallon landscape quality potted plants (these specimen do NOT have to be show quality). For those who submit plants, PLEASE use a separate tag to identify the genus, name of the plant and your name. There will be an attendant at each landscape plot to answer questions along with signage to explain the exhibit. Presentation, demonstrations, and guest speakers will be in the Garden Center and will include the following: Container gardening Propagation Pest control and fertilization Pet and child friendly plants Color coordinated gardens Native plants The show chairs Sandy Chase (818-367-0864) or Joyce Schumann (818-705-3224) need to know by Thursday, February 4 the number of plants, genus and category you are willing to loan for the construction of the exhibits. Vendors will be selling landscaping plants in addition to their usual merchandise. The Bromeliad Society will participate in this Festival as they have in the past. Of Special Importance: Publicity is critical to the success of this Festival. Flyers, post cards, and email announcements will be distributed. Retail nurseries and other garden centers will also be contacted. Involvement of all LACSS members is critical to the success of the Festival.

Los Angeles Cactus and Succulent Society Cacti of the Month February 2010 - Monotypic Cacti Monotypic cacti or distinguished from other genera by the fact they have only one species per genus. This is not the case with most cacti and succulents where most genera have several species and/or subspecies associated with the genus Monotypic cacti are endemic to their environments and are geographically more likely to be found in areas of Mexico, southern California, Arizona, New Mexico, and southwestern Texas. leaves Flower emerge from the tips of new tubercles in the spring. Found in Southern Bolivia and northwestern Argentina, at higher elevations is Blossfeldia liliputana. This is a solitary or clumping miniature cactus that produces 1/2 inch stems or globular growths. This genus tolerates colder conditions than most cacti and require little or no water during the winter months One of the more remarkable instances of endemic monotypic cacti is in the Sonoran desert where Carnegiea gigantea forests (Saguaro) are found. Originating in the dry climate condition of the Sonoran Desert, these specimen dominate the landscape. Blossfeldia liliputana Carnegiea gignatea forest The following describes other monotypic cacti genera and the plants that comprise a more collective category of plants. Leuchtenbergia principis is found in Mexico and is a specimen that looks more like an Agave than a cacti. The tubercles are approximately 3 to 4 inches in length and look much like agave Obregonia denegrii is another monotypic cacti that is popularly known as the artichoke cactus. Found in Mexico Obregonia's can tolerate extreme cold for short periods of time. This is a solitary and globular plant that produces greyish green to dark green, triangular tubercles. A dome of white wool forms at the apex of the plant. Ortegocactus macdougalli is endemic to Oaxaca Mexico and grows on limestone rock cropping at heights up to 6,000 feet.
gypsum. Geohintonia's are typically solitary plants with numerous ribs. Juvenile specimen are normally globose becoming more columnar as they mature. Plants are typically dark green covered by a glaucous pruina. Geohintonia spines are short, triangular, curved, and as they age brittle. This plant is endangered and is considered a prize specimen in a collection. Geohintonias are named for its discoverer George Hinton. Ortegocactus macdougalli Closely related to the genus Mammillaria, this plant is often grafted to avoid growing difficulties associated with its own root system. Another potential problem with Ortegocactus is the Orange discolorations that frequently appear at the base of stems. Geohintonia mexicana The last example of monotypical cacti presented in this article is Geohintonia mexicana. Originating from the Nuevo León: Sierra Madre areas or Mexico, this plant grows on vertical cliffs filled with References D. Hunt, The New Cactus Lexicon C. Innes and C.

Los Angeles Cactus and Succulent Society Succulent of the Month February 2010 - Adromischus, Anacampseros & Avonia Adromischus trigynus Adromischus is closely related to the genus' Cotyledon and Tylecodon. There are 29 recognized species of Adromischus all found in southern Africa. When grown in cultivation they require at least partial shade, especially in hotter climate. This plant forms clumping succulent rosettes and expands horizontally. Propagation occurs from stem or leaf cutting as well as from seed. Distinctive markings and colored leaves are characteristic of this genus. Avonia quinaria ssp. alst Anacampseros is a genus that formerly housed a much larger number of species including the genus Avonia. Anacampseros are found in South African. They form clumping rosettes of succulent leaves. A small caudex forms as the plant ages. Flowers bloom periodically during the summer on sunny days only. The genus Avonia originates in South African in Great Namaqualand andbushmanland. Avonia form a woody caudex, approximately one inch high, which expands as the plant matures. Leaves emerge from the top of the caudex. This plant typically requires partial shade in cultivation and can be sensitive to frost or colder conditions. Although listed as a deciduous plant, many specimen retain their leaves all year long. Flowers are carmine red, white, or pink. Avonia flowers are self-fertilizing and can generate seed if you have only one plant. Anacampseros Steve Frieze, February 2010
BOARD OF DIRECTORS 2010 President: Artie Chavez Vice President, Programs: John Martinez Vice President, Plant of the Month: Manny Rivera Vice President, Special Events: Doug George Treasurer: Sandy Chase Secretary: Helen Frank Chronicle Editor: Phyllis Frieze We Want Your Stories The Board of Directors has had several discussions on the content of the Chronicle. They thought it would be good to have some fresh ideas about the world of cactus and succulents. One of the suggestions was for volunteer guest columnists write an article focusing on their special interests. We are confident that many of you could easily write 500 words on your favorite topic, such as how I got interested in cactus and/or succulents, my favorite potting soil, my favorite plant (or least favorite), and why. If we had a person a month do one article to be published in the Chronicle it would enhance everyone s knowledge and can be used as a diversified learning tool. So who will step up and author the first guest column? We want to publish the first article in the March 2010 Chronicle and hope that all of you will contribute to this new feature. Please email your article to me by January 20, 2010 so it can be included in the March 2010 issue. It would be helpful if you could let me know the subject you will write on and what month it can be sent to me for inclusion.

From the Stacks of the Library - February 2010 By Joyce Schumann LACSS Librarian Please stop by at the next meeting. As we continue into the new year, I would like to thank all of our members for their continued interest and support of our Library. It is for all of you. Call or email me if you have an interest in a particular book and I will bring it to the next meeting. You may have seen a book somewhere (library, bookstore, other club, etc) that you think should be in our collection. Let me know - we will consider it for purchase. You are the eyes and ears for future book acquisitions! Speaking of new books (nice segue huh?), we will be featuring two new books this month. The first book is Pachyforms Volume 2 BONSAI SUCCULENTS by Philippe de Vosjoli and Rudy Lime. This book contains a notes and photographs supplement to Volume 1 plus an excellent discussion on the difference and similarities of bonsai and succulents. All aspects of plant selection through maintenance are covered and will be good reading by those who are interested in pachyforms, staging, and bonsai. The second book is titled LITHOPS Flowering Stones by Desmond T. Cole. Up to now our only book dedicated to lithops has been the small book by Fearn. Now we have 100 pages of discussion on morphology, nomenclature, habitat and cultivation. That s followed by 150 pages of superb photos and descriptions. This is a fantastic reference for all those plants that are too cute for their own good! For the future, the Board is considering regular acquisitions of the British and South African periodicals in addition to the CSSA Journal. Watch this space for further news Last but not least, the Library List (by author and by subject) has been updated and is available. Stop by the library and pick them up and while you re there check out a book. See ya at the meeting. Joyce the Librarian
